A subject cannot be a *predicate* as I understand it, because the
predicate is always the piggy-in-the-middle as far as the triple is
concerned, but of course an instance of *property* (i.e. rdf:type(?x,
rdf:Property)) can be. I think that Nikita was in fact asking if a
property can be used as a subject. The answer, therefore, is "yes".
